STRUT-TI'E l-'OR PREVENTING CREEPING OF RAILS.

SPECIFICATION forming part of Letters Patent No. 611,101, datedSeptember 20, 189.8.

Application iiled May l0, 1898. Serial No. 680,309. (No model.)

To all whom, t may concern,.-

Be it known that I, ADoLPHUs BoNzANo, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented a certain ImprovedStrut-Tie for Preventing the Creeping of Rails, of which the followingis a speciiication.

The object of my invention is to prevent the longitudinal creeping ofrailway -rails upon the ties caused by the passage of trains thereover.This object I attain by providing a device which is secured to the railsand to the ties in a manner fully described hereinafter, reference beinghad to the accompanying drawings, in Which- Figure 1 is a perspectiveview of my improved device for preventing Ithe creeping of 2 is a sideview showing the device in position. Fig. 3 is a plan view with the railin section. Fig. 4 is a View of a modification, and Fig. 5 is a view ofa modified form of strut-tie.

Rails of railway-tracks are solaid that they are free to expand andcontract, and consequently are also free to creep, which is alongitudinal movement caused by the rollingstock passing over them.While the rail must be free' to expand and contract, the creeping must be checked. I accomplish this in the following manner:

A is the rail of a railway-track.

B are the ties, to which the rail A is secured by spikes b. I perforatethe web o, of the rail at or about the center of its length and secure`thereto a strut-tie D, which is also secured to the ties.

The strut-tie is made, preferably, in the` form shown in Fig. 1, havinga flat central section d, adapted to rest against the web of the rail,and flat end sections d d at right angles thereto and adapted to rest onthe ties and connected to the central section d by members d2. Thestrut-tie is of such alength that the end sections will rest on twoties, as Shown, with an intervening tie under the center where thestrut-tie is secured to the rail.

The strut-tie D is secured to the rail by a bolt or rivet c and to theties by spikes or screws ff.

I prefer to turn a lip d4 on each end of the strut-tie D,Which enter thetie and thus take the strain off of the spikes f and give a wideresisting-surface against longitudinal pressures.

I prefer to make the strut-tie by cutting a metal bar to the properlength and then bending it to shape, as shown in Fig. 1; but othermethods of making the device may be employed without departing from myinvention.

It will be noticed that when the strut-tie is in position if the railhas a tendency to move longitudinally in one direction one of themembers cl2 will hold .it under tension, while the other will hold itunder compression. Thus the entire strut-tie is brought into action andthere is no tendency to impart lateral motion to the rail, as one memberd2 counteracts the other member.

The strut-ties maybe placed one on each side of the rail and boltedtogether and to the rail, or the strut-tie may be made in two parts, asshown in Fig. 4, one part D on one side of the rail and the other partD2 on the other side of the rail.

fasteningof the strut-tie to the cross-tie B at the points shown doesnot interfere with the rail-spikes, and the ties will not tip undereither torsional or compression strains.

In some instances the strut-tie may be made as shown in Fig. 5, havingextended members d3, being of such a length as to rest each upon twoties, and I have shown in this iigure the central portion having twoholes for two securing-bolts. It will be understood that the strut-tiemay have one or more boltholes and one or more holes for the spikes tosecure it to Athe ties and that while I have shown the strut-tie made ofa plain bar a flanged or other-shaped bar may be used withi IOO membersecured to-a cross-tie, so that each end of thenail is .f1-ee toexpandoi" contract, substantially as described.

The combination of a rail, cross-ties on which the rail is mounted, astrut-tie having a central section secured to the web of the rail, endsections-secured to cross-ties and twisted members connecting the endsections to the central section, said strut-tie being of 1o such tlength as to extend from one tie to anothei` with a itie intervening,substantially as :described ADOLPHUS BONZANO.
